Abstract

Stud structure for main transformer fire wall, it is mainly made up of the stud in fire wall and fire wall, described stud is cast on the basis of fire wall, and is made into integration in fire wall, and dowel is reserved with the stud and crab-bolt at the top of stud, for connecting stud and framework is made;Beam of the described fire wall above fire prevention foundation of wall, fire-proof wall and fire-proof wall, is made into integration in fire wall by described stud, and the capital of the stud is back taper capital, and described crab-bolt is embedded with the back taper capital;Described stud is formed by post reinforcing bar, cushion block and the concreting tied up, and the inside of stud is fixedly connected with stud surface with the dowel electric welding of crab-bolt by steel pipe and fixes crab-bolt with doughnut-shaped steel plate;The utility model compared with prior art, draws the advantage of arch without beam cap, and rationally make use of fire prevention wall column, on the basis of the pressure transmission suffered by framework suspension column to fire wall.

Description

Stud structure for main transformer fire wall
Technical field
The utility model relates to a kind of stud structure for main transformer fire wall, and as the support of truss column, with Solve the problem of framework column foundation of generation is nowhere put due to space limitation.
Background technology
Land resource is valuable, in process of construction, how to be saved floor occupying area by optimizing structural shape, and less Width increase construction investment, which is one, the problem of realistic meaning and practical value.In order to preferably implement State Grid Corporation of China " two Type one is changed " installation guideline policy, protect farmland, economize on resources, research is carried out and excellent to the structural shape of transformer station
Change, and then compress transformer station's planar dimension, reduce permanent take up an area.
Framework is one of most important structures of transformer station, and its structural shape is thrown with general layout, construction period, engineering Money is closely bound up.Transformer substation framework basis uses isolated footing, although its structure reasonable, there is also floor space The problems such as many, construction process requirement is high, the construction period is long.
When field geology is complicated, framework basis often uses pile foundation, and the expense of pile foundation is far more than independent base Plinth;In this case, how according to actual conditions suit measures to local conditions to propose a kind of economical rationality, spaces compact new framework Supporting construction is particularly important.
The content of the invention
The purpose of this utility model is to overcome above-mentioned not enough there is provided one kind is simple in construction, easy to install and use, By the use of fire wall stud as the important connection of truss column and Force transmission partses, can be applicable on fire wall vertical truss column for main transformer The stud structure of fire wall.
The purpose of this utility model is completed by following technical solution, a kind of stud knot for main transformer fire wall Structure, it is mainly made up of the stud in fire wall and fire wall, and described stud is cast on the basis of fire wall, and in fire wall In be made into integration, dowel is reserved with the stud and anchor at the top of stud, for connecting stud and framework is made Bolt.
As preferred:Beam of the described fire wall above fire prevention foundation of wall, fire-proof wall and fire-proof wall, in fire prevention It is made into integration within the walls by described stud, and the capital of the stud is back taper capital, it is pre-buried in the back taper capital There is described crab-bolt.
As preferred:Described stud is formed by post reinforcing bar, cushion block and the concreting tied up, and the inside of stud leads to The dowel electric welding for crossing steel pipe and crab-bolt is fixedly connected with stud surface and fixes crab-bolt with doughnut-shaped steel plate.
The utility model compared with prior art, draws the advantage of arch without beam cap, and rationally make use of fire prevention wall column, On the basis of the pressure transmission suffered by framework suspension column to fire wall, take up an area with saving, shorten the duration, process the side such as quick for installation The advantage in face, is that country saves valuable land resource, with certain economic and social benefit.
Brief description of the drawings
Fig. 1 is structure section figure of the present utility model.
Fig. 2 is the utility model the utility model crab-bolt schematic diagram.
Fig. 3 is the utility model the utility model stud 1-1 sectional drawings.
Fig. 4 is the utility model stud arrangement of reinforcement.
Embodiment
The utility model is described in detail below in conjunction with accompanying drawing:Shown in Fig. 1-4, one kind described in the utility model For the stud structure of main transformer fire wall, it is mainly made up of the stud in fire wall and fire wall, and described stud is cast in On the basis of fire wall, and be made into integration in fire wall, be reserved with the stud dowel and be made it is at the top of stud, Crab-bolt for connecting stud and framework.
Shown in figure, the beam of described fire wall above fire prevention foundation of wall, fire-proof wall and fire-proof wall, in fire prevention It is made into integration within the walls by described stud, and the capital of the stud is back taper capital, it is pre-buried in the back taper capital There is described crab-bolt.
Stud described in the utility model is formed by post reinforcing bar, cushion block and the concreting tied up, the inside of stud Stud surface is fixedly connected with the dowel electric welding of crab-bolt by steel pipe and fixes crab-bolt with doughnut-shaped steel plate.
Embodiment:
1)The construction of fire wall and stud, the construction of fire wall should be carried out by absolute altitude, first construction fire prevention foundation of wall, then be poured Fire prevention wall column, then first builds a wall and pours beam afterwards, is built by laying bricks or stones by design drawing layering, and is fully connect with building block by reserving dowel in post Touch.Construct the part when, especially it is noted that sequence of construction, such as first build a wall and pour beam afterwards.
2)The construction of stud, is cleared up post root after the colligation of post reinforcing bar, cushion block installation.Back taper capital is propped up Mould, and adjust perpendicularity.Mortar leakage prevention processing is carried out to template.After casting concrete, form removal is carried out after certain time.
3)The construction of crab-bolt, crab-bolt is reserved at the top of stud, and pre-buried depth presses design requirement.Inside stud by steel pipe with Crab-bolt electric welding is fixed, and crab-bolt is fixed in stud surface with 6 thick and circular steel plates, the wide 80mm of ring flat-plate.It is high that column cap reserves 50mm, in capital After framework leveling is fixed, pour using C35 microdilatancy fine-stone concretes are secondary and (inside mix 8%ACII type calcium sulphoaluminates cement expansive material), Pressure grouting.
The utility model is applied in 1000kV Zhe Zhong transformer stations fire wall.
